Abstract
The utility model relates to a novel capacitor box which comprises a capacitor box main body. Three installation supports are arranged in the capacitor box main body, a plurality of current transformers are arranged on a first installation support, the current transformers are respectively connected with knife switches, the knife switches are connected with vertical buses, a plurality of alternating current contactors are arranged on a second installation support, and a plurality of electric reactors are arranged on a third installation support. The electric reactors are increased on an original capacitor box, and the novel capacitor box can remarkably restrain harmonic waves and is stable in operation, small in operation noise and long in service life.
Description
Technical field
The utility model relates to a kind of regulator cubicle, relates in particular to a kind of novel capacitor cabinet.
Background technology
The basic reason that harmonic wave produces is because due to the nonlinear load.When electric current is flowed through load, not linear with added voltage, just form non-sinusoidal current, thereby produce harmonic wave, use the enterprise of the nonlinear-loads such as great power conversion circuit all can produce serious harmonic wave.Such as arc furnace, intermediate frequency furnace, coreless induction furnace, frequency converter etc.Harm of harmonic: 1 high order harmonic component can make voltage and the current waveform distorted of electrical network, the harmonic voltage of same frequency and harmonic current will produce active power and the reactive power with subharmonic in addition, thereby the reduction line voltage increases line loss, the waste net capacity; 2, affect the reactive-load compensation equipment of electric power system, harmonic wave causes transformer station's high-voltage capacitance overcurrent and overload when injecting electrical network easily, and under the harmonic wave occasion, capacitor box is switching normally, and more serious asks under the condition, and capacitor box can further amplify mains by harmonics; 3, affect the stability of equipment, especially to protective relaying device, endanger especially big; 4, the existence of harmonic wave can cause the asynchronous motor decrease in efficiency, and noise increases; Make low voltage switchgear produce misoperation; Normal communication to industrial enterprise's automation causes interference, affects the accuracy of power electronics measuring equipment; 5, the existence of harmonic wave can make the copper loss of power transformer and iron loss increase, and directly affects use capacity and the service efficiency of transformer; Also can cause transformer noise to increase, shorten the useful life of transformer.
The utility model content
The utility model for overcome the above problems provide a kind of simple in structure, production cost is low, the novel capacitor cabinet of working stability, inhibition harmonic wave.
The technical solution of the utility model is: comprise the capacitor box main body, be provided with three mounting brackets in the described capacitor box main body, mounting bracket one is provided with a plurality of current transformers, be connected with respectively knife switch on the described current transformer, described knife switch is connected to perpendicular bus, described mounting bracket two is provided with a plurality of A.C. contactors, and mounting bracket three is provided with a plurality of reactors.
Described knife switch connects one and is arranged on the outer knife switch direction board of capacitor box main body, and described knife switch direction board setting angle is 120 degree.
The utility model adds reactor at original capacitor box, can play obvious effect to harmonic restraint, working stability, little, the long service life of operating noise.
